My provider offers a Speedtouch 780WL (locked) as CPE which provides two FXS ports. I wanted to use a software based PBX so I bought a couple of SPA 3102 Gateways. After a little experimenting, I found that Norway's disconnect tone pattern (as it is provided in the Cisco ATAs manual) seemed to work the best with the 780WL's FXO ports. However, to my surprise it turned out that the SPA will detect the disconnect tone while the line is ringing, but will fail to do so during a call! Here's an example:
Inbound call ---> nobody answers the phone ---> Remote caller hangs up ---> SPA successfully detects disconnect tone
Inbound call ---> call picked from a SPA941 ----> After the conversation ends, the remote caller hangs up first ---> SPA3102 fails to detect disconnect tone.
In the latter case, I can hear the tone through the SPA941's handset, the VoIP call is not terminated and the SPA3102 still lists "PSTN Line"'s hook status as "hook off"...
Does anybody have any idea on what is to blame here? Better off, does anybody have SPA settings that work with the Speetouch?
Downgrade it and you will be fine

Dear sir, please revert to 5.1.7. There is an issue related to tone detection which may be related to your case. Let us know the results.
What firmware version in your SPA3102?
